Solid State Contactor US-N Series Features

  • Optimal for motor load in high-frequency switching, such as on a transport line, etc. Can also be used with a heater load.
  • The load current switching operation is performed by a semiconductor switching element, and as there are no mechanical parts, a long life with highly frequent switching can be achieved.
  • As there are no mechanical movable parts or abrading parts, no abrasion dust or contact consumption dust is created, resulting in clean, noiseless and comfortable use.
  • Operation indicator lamp on the front surface allows users to see the operating voltage input status at a glance.
